AlfaPort

AlfaPort is a controlled sand screen with SSD that allows switching the inflow mode through the sand screen using a special sliding switching clutch.

AlfaPort - includes a two-position switching clutch, specially designed for sand screen control. The device is controlled using a special tool that is run into the well to switch the port to the required position. Combined with wire-wrapped sand screens, this device provides a complete controllable sand screen solution. The AlfaPort valve can be equipped with fittings of various diameters to provide the required inflow mode through the controlled sand screen device. Operational decisions on switching AlfaPort devices can be made based on PGI research data, for example, using multi-sensor PLT equipment. Another option for making a decision on the management of AlfaPort devices is the use of monitoring data using the technology of chemical tracers.

• Flow control along a horizontal well
• Elimination of zonal gas and water breakthrough
• Use of the device in steam or water injection mode
• Use for safe running of the liner with the possibility of further technological flushing
• Control the ​​water and gas breakthrough area in order to prevent it
• Zonal inflow management to improve well productivity

• The controlled devices are compatible with all types of sand screens, using a standard type of thread
  
• Robust device, high loads, applicable at high temperatures and pressures
  
• Opening and closing ports in one run of the switching tool
  
• It is allowed to use fittings of different diameters to change the throughput of the device
  
• Anti-corrosion coating, protection against leakage into the inner cavity of the clutch
  
• AlfaPort can be used in combination with inflow markers (tracers)
